Abstract: Eine Anordnung zur Erzeugung von Eigenresonanzschwingungen eines mechanischen Schwingsystems (10) enthält einen elektromechanischen Schwingungserreger (20), der bei Erregung durch ein elektrisches Erregungssignal (E) eine das Schwingsystem (10) in mechanische Schwingungen versetzende Antriebskraft erzeugt, einen als Wegsensor ausgebildeten Schwingungssensor (25), der die mechanischen Schwingungen des Schwingsystems (10) abtastet und in ein elektrisches Sensorsignal (A) umwandelt, und eine Erregungsschaltung (30), die das Sensorsignal (A) empfängt und das elektrische Erregungssignal (E) mit der Frequenz des Sensorsignals (A) zu dem Schwingungserreger (20) liefert. Die Erregungsschaltung (30) enthält einen Phasenregelkreis (31), der die Phasenlage des Erregungssignals (E) in Abhängigkeit von der Phasenlage des Sensorsignals (A) regelt. Eine Phasenschieberschaltung (37) erzeugt eine Phasenverschiebung von 90° zwischen dem Sensorsignal (A) und dem Erregungssignal (E), so daß die Phasenbedingung für die Erregung der mechanischen Schwingungen bei der Eigenresonanzfrequenz des mechanischen Schwingsystems erfüllt ist. Dies ermöglicht die Einhaltung der Eigenresonanzfrequenz des mechanischen Schwingsystems mit sehr guter Genauigkeit und großer zeitlicher Stabilität auch bei Schwingsystemen hoher Güte.

Abstract: In a user-interactive display-based system (FIG. 1), the present invention permits an automatic display of a repertoire of command items (FIG. 4) most likely to be utilized by a user, thus providing one-touch access to such items without requiring either explicit programming of a command repertoire or a search by the user through the history of previous commands. This is accomplished (FIG. 2) through the use of three heuristics which consider frequency of command use (300), recency of command use (310), and previously failed commands (320). These heuristics may be implemented either separately or together in the system.

Abstract: A polyarylene sulfide having a low content of electrolytic ions is economically recovered from a mixture consisting mainly of polyarylene sulfide and an alkali metal halide which mixture is obtained by reacting a polyhaloge­nated aromatic compound and an alkali metal sulfide contain­ing water in an organic polar solvent, by dehydrating the mixture by distillation, mixing the dehydrated mixture with a solvent which is a bad solvent for both polyarylene sulfide and alkali metal halide and which is soluble in the organic polar solvent to prepare a slurry consisting essentially of the polyarylene sulfide and the alkali metal halide, subjecting the slurry to solid-liquid separation, washing the resultant cake with the bad solvent, drying the cake, adding water to the cake to wash away the alkali metal halide through dissolution, and subjecting the slurry to solid-liquid separation to recover polyarylene sulfide. Such a polyarylene sulfide is particularly useful for use in electronic and electric components and molded articles such as films, sheets and fibers.

Abstract: This radar system makes it possible to collect complete stereo data in a single pass by utilizing an orbiting, side looking, bi-static, synthetic aperture radar. This system utilizes at least two orbiting spacecraft (10-12) in synchronous parallel orbits with each other and separated by a tether (14). A transmitter (18) transmits radar signals (26) to a planet's surface which are reflected back (28,30) and received by two receivers (22), one carried by each spacecraft. When the signals are combined, the layover produces a three dimensional picture in which vertical height information may be determined.

Abstract: The invention relates to a process and apparatus for boiling flowing liquids such as liquefied gases in a heat exchanger in which a circulating flow is occurring, such as in reboiler-condensers in air separation and similar cryogenic plants or other appications where a high efficiency for boiling heat transfer is beneficial. The important feature of the process and apparatus is the use of two sequential heat transfer zones having different pressure drop and heat transfer characteristics in the same boiling channel (30), the first zone (regions 1 + 2) having an overall high-convective-heat-transfer characteristic and an overall higher pressure drop characterictic and comprising a plurality of sub-zones, each sub-zone sequentially having a lower pressure drop than the previous sub-zone and the second zone (32) having a lower pressure drop and an enhanced nucleate boiling heat transfer characteristic.

Title: Sensor zur Messung des Stromes oder der Spannung von auf einem Referenzsubstrat vorhandenen elektrisch leitenden Schichten
Inventor: SCHOBER KONRAD DIPL-PHYS
IPC: G01R27/02
Filed: 1988-03-17
Abstract: Um den Widerstand oder die Temperatur der auf einem Referenzsubstrat (1) bei der Beschichtung des Substrates abgeschiedenen elektrisch leitenden Schichten zu messen, wird ein Sensor verwendet, der aus einem Referenzsubstrat (1) und auf dem Referenzsubstrat aufgesteckten Meßplättchen (10) und Trägerplättchen (6) besteht. Das Referenzsubstrat (1) ist mit Leiterbahnen (2) versehen, zwischen denen bei der Beschichtung die elektrisch leitenden Schichten entstehen. Wenn über diese leitenden Schichten ein Strom fließt, dann kann zu dessen Messung oder zur Messung des Spannungsabfalles ein Meßsignal an den Leiterbahnen (2) über die Meßplättchen (10) abgenommen werden. Diese Meßsignale werden über in einem Substrathalter angeordnete Kontaktelemente einer Meßanordnung zugeführt und ausgewertet. Dazu wird der Sensor auf den Substrathalter im Bereich der Kontaktelemente aufgelegt, wobei eine sichere Auflage mit Hilfe der Trägerplättchen (6) erreicht wird. Der Vorteil des Sensors besteht darin, daß er eine geringe Höhe aufweist, direkt auf dem Substrathalter aufliegt, während die weiterhin erforderliche Meßanordnung im Substrathalter oder am Substrathalter dort angeordnet werden kann, wo beim Beschichten die kühlste Stelle des Substrathalters ist.

Anschließend wird der Objekthalter (5) mit dem daran haftenden Probekörper (6,7) in eine Kraft-Weg-Meßeinrichtung gebracht und das freie Ende der Faser (6) an einer in Faserrichtung verfahrbaren Einspannvorrichtung (10) fixiert. Bei dem Zugversuch werden nun die auf die Faser einwirkende Zugkraft mittels des Kraftaufnehmers (2) und gleichzeitig der von der Einspannvorrichtung (10) zurückgelegte Weg durch den Wegaufnehmer (13) in entsprechende elektrische Signale umgesetzt und ausgewertet.

Abstract: Disclosed are novel high flexural modulus polyurethane plastics wherein a polyisocyanate and a particular combination of extenders including cycloalkane diol are reacted optionally in the presence of a minor proportion of high molecular weight polyol. 
     The polymers have outstanding resistance to high temperatures thereby expanding their utilities into higher temperature end-use environments than related prior art materials. Certain members of these new polymers are also possessed of outstanding optical clarity which thereby provides a combination of properties heretofore not available in a polyurethane. These polymers are easily melt-fabricated notwithstanding their inherent high temperature properties.

Abstract: An improved thermal circuit breaker is disclosed, featuring a U-shaped bimetallic element which latches an escapement locking arm which holds a spring biased moving contact against a fixed contact when the breaker is in the contacts closed position. The improved thermal element has terminal portions which are of lesser electrical resistivity than are other portions of the element. The relative orientation of the metals of the bimetallic element in the terminal portions are reversed with respect to their orientation in the remainder of the bimetallic element. In this way ambient temperature compensation is provided to the breaker such that the current rating of a given breaker does not vary with variation in ambient temperature.

Abstract: A teletext decoder includes a background or buffer memory (45) operating as a first-in, first-out (FIFO) memory. The buffer memory (45) is used for storing a large number of teletext pages. A given video line that contains teletext information is identified as such by the detection of part of a clock run-in sequence followed by the framing code. The video line is then stored in the background memory (45). After a user page request occurs, the background memory (45) is read-out by a data processor (30) operating in a full channel mode of operation for obtaining the information of the requested page. As long as the read-out operation has not been terminated, incoming teletext data is stored in the background memory (45). This enables teletext data received prior to termination of the read-out operation to be read out and processed by the data processor.
